Scientists in Taiwan have updated a comprehensive list of powdery mildew fungi that infect plants, adding 29 new host plant records. They identified 13 different species of these fungi using both traditional microscopy and modern DNA sequencing techniques. This updated list is important for farmers and gardeners to identify and manage powdery mildew diseases on their crops and plants.

This study examined a collection of powdery mildew fungi preserved in a university herbarium and used DNA analysis to identify which specimens had been misidentified over the years. The researchers found that about 83% of the specimens had incorrect identifications and discovered four completely new species that look very similar to known species but are genetically distinct. The findings show that old museum collections are valuable resources for discovering hidden biodiversity and that we should preserve these collections rather than discard them.

Researchers updated Taiwan’s list of powdery mildew fungi, which are harmful plant pathogens affecting crops and trees worldwide. By collecting specimens from various locations and analyzing them using genetic sequencing and microscopy, they identified 29 new host-fungus combinations, with six Erysiphaceae species documented in Taiwan for the first time. The updated checklist now includes approximately 109 powdery mildew species known to affect 246 different host plant species across 75 plant families in Taiwan.
